This paper introduces Covhisto, a web application for visualizing and analysing changes across multiple versions.

METHODS: Covhisto uses crosswalk tables published by the German Federal Institute for Drugs and Medical Devices (BfArM) and data processing pipeline to track changes between ICD-10-GM and OPS versions. Key features include methods for following individual code histories and analyzing structural changes in the coding systems.

RESULTS: Covhisto allows users to trace code evolution and identify changes not automatically captured. Unlike existing solutions, Covhisto creates a ConceptMap across all versions, offering a comprehensive view of changes over time.

CONCLUSION: Finally, Covhisto complements existing solutions by making complex code changes more transparent and easier to understand, supporting healthcare professionals and researchers in their analyses and promoting interoperability of healthcare data.</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/40899540?dopt=Abstract</style></custom1></record></records></xml>
